ABSTRACT

An umbrella supporting mount can be easily and quickly secured to a flat surface of a table or roof of a vehicle in a stable and firm manner without shaking at all. The supporting mount has an integrally punched metal lid of proper height and is equipped with a plurality of vent holes and a pair of symmetric mounting holes on the vertical periphery thereof so as to permit a cranked driving control shaft having a handle at one end to be located in a hollow interior of the lid. A driven unit integrally made of hard plastics consists of a circular base board and a vertically extended block having a driving hole disposed at the center thereof. The circular base board of the driven unit is partially wrapped around by a sucking attachment which is made of flexible rubber and has a peripheral skirt defined at the bottom edge thereof. So, a cranked section of the cranked driving control shaft can be engaged with the driving hole of the driven unit and the activation of the driving control shaft results in the lift up of the driven unit to force air in the skirted area of the sucking attachment out of the lid via the vent holes so as to produce a vacuum effect for firmly fix the supporting mount to a flat surface.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to an umbrella supporting mountwhich can be easily and quickly secured to a flat surface of a table orroof of a vehicle in a stable and firm manner without shaking at all.The supporting mount has an integrally punched metal lid of properheight and is equipped with a plurality of vent holes and a pair ofsymmetric mounting holes on the vertical periphery thereof, permitting acranked driving control shaft having a handle at one end to bepositioned in a hollow interior of the lid. A driven unit integrallymade of hard plastics consists of a circular base board and a verticallyextended block having a driving hole disposed at the center thereof. Thecircular base board of the driven unit is partially wrapped around by asucking attachment which is made of flexible rubber and has a peripheralskirt defined at the bottom edge thereof. So, a cranked section of thecranked driving control shaft can be engaged with the driving hole ofthe driven unit and the activation of the driving control shaft resultsin the lift up of the driven unit to force air in the skirted area ofthe sucking attachment out of the lid via the vent holes so as toproduce vacuum effect for firmly fix the supporting mount to a flatsurface.

[0002] There are two commonly seen prior art umbrella supporting mountsor stands, one is a dome shaped metal or concrete block having anumbrella supporting post located at the center thereof; and the other isa table supported by a cylindrical supporting post and at the center ofthe table is located an umbrella insertion hole so as to permit anumbrella to be retained in place. Both of such prior art supportingmounts have the following disadvantages:

[0003] 1. The weights and the size of the supporting mounts arerelatively too heavy and bulky for easy transportation and storage.

[0004] 2. The table structure with the supporting post occupies too muchroom and is not widely applied to different events.

[0005] 3. The umbrella and the supporting mount are designed in such amanner that they can not be carried around as a whole, making thepracticability of such supporting mount poor.

SUMMARY OF THE INVENTION

[0006] Therefore, the primary object of the present invention is toprovide an umbrella supporting mount which is equipped with a crankeddriving control shaft mounted to a lid and engaged with a driven unitpartially wrapped around by a flexible sucking attachment. The lidhaving a plurality of vent holes is easily engaged with the flexiblesucking attachment having a bottom peripheral skirt whereby theactivation of the driving control shaft results in the expelling of airunder the skirted area of the sucking attachment so as to make thesupporting mount to be removably fixed in place.

[0007] Another object of the present invention is to provide an umbrellasupporting mount which can be readily disposed on a garden table or theroof of a vehicle in a firm and stable manner without shaking at all.

[0008] One further object of the present invention is to provide anumbrella supporting mount which can be easily and speedily secured inplace and dismantled for storage; and the supporting mount is also canbe attached to the end of an umbrella for use as a handle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Referring to FIG. 1, the umbrella supporting mount of the presentinvention comprises a lid 10, a driven unit 20, a sucking attachment 30,a driving control shaft 40, a tubular sleeve 50 and two end caps 60. Thelid 10 is a metallic piece integrally punched into a cover in a circularshape with of a proper height. There are two symmetric round mountingholes 11 on the opposite positions of the circular periphery thereof. Aplurality of vent holes 12 are disposed between the round mounting holes11. The lid 10 has a hollow interior 13. The driven unit 20 isintegrally made of hard plastics and has a circular base board 21 at thebottom thereof and has a vertically projected block 22 at the centerhereof. At the center of the block 22 is disposed an axially extendeddriving hole 23 which has a flat bottom base and two symmetric arcshaped sides 231 extending to the summit of the driving hole 23. Thesucking attachment 30, a circular element made of elastic rubber,consists of a top and bottom section; the former has an engagementcavity 31 with a stepwise projection 32 disposed at the center forpartially wrapping up the circular base board 21 of the driven unit 20.The periphery of the bottom section is provided with a supporting skirt33 having a larger diameter than that of the top section and a slopedinward peripheral plane 34. The sloped plane 34 forms a large recessedarea 35 at the center of the bottom section.

[0016] The driving control shaft 40 is integrally formed having a thinand elongated driving stick 41 at both ends and a cranked middle section42 provided with a smoothed face 421 in conformance to the arc shapedinner wall 231 of the driving hole 23. An actuation handle 43 extendsvertically from one end of the driving stick 41. The tubular sleeve 50is made of elastic rubber and the two end caps 60 are respectively ashort cylinder with an engagement opening 61 at one end.

[0017] In assembly, as shown in FIG. 2, the handle of an umbrella isinserted into an elastic holding tube A and the umbrella is secured tothe top center of the lid 10. The tubular sleeve 50 is led into thedriving control shaft 40 and is moved next to the actuation handle 43.Then the driving stick 41 is led into the round hole 11 of the lid 10and further into the driving hole 23 of the block 22 of the driven unit20 wrapped up by the sucking attachment 30 with the cranked middlesection 42 confined within the driving hole 23. At last the drivingstick 41 sticks out of the opposite round hole 11 of the lid 10 with theend cap 60 attached to the end thereof for limiting purpose. At then theengagement cavity 31 of the flexible sucking attachment 30 is outwardlypulled to such an extent that the hollow interior 13 of the lid 10 canbe stuffed thereinto. Another end cap 60 is secured to the end of thehandle 43 of the driving control shaft 40 to complete the assembly.

[0018] Referring to FIG. 3, it shows the present invention is put in anon lift-up state and in FIG. 4, the same is put in a lift-up state. Thedriving control shaft 40 is restrained in place by the tubular sleeve 50and the end caps 60, so, in operation, the driving control shaft 40 willnot disengage from the round mounting holes 11 of the lid 10.

[0019] As the driving control shaft 40 is operated in a lift-up state,the handle 43 is cranked to get the middle cranked section 42 of thedriving stick 41 spun upwardly, with the smoothed face 421 in urgingabutment against the arc shaped inner wall 231 of the driven unit 20.The hard circular base board 21 of the driven unit 20 can cause therecessed area 35 of the sucking attachment 34 to lift upwardly,resulting in the air in the hollow interior 13 and the engagement cavity31 will be expelled out of the lid 10 via the vent holes 12. Therecessed area 35 comes into a vacuum state so as to make the supportingskirt 33 of the sucking attachment 30 suck firmly on a surface to whichthe supporting mount is to be fixed in a ready, stable and firm withoutshaking manner, such as a garden table or the roof of a vehicle, asshown in FIGS. 5, 6.

[0020] It can be apparently seen that the above embodiment has thefollowing advantages in practical use:

[0021] 1. The driving control shaft 40 is firmly retained in place bythe tubular sleeve 50 and a pair of end caps 60 having an engagementopening 61 when engaged with the lid 10 which is firmly mounted toengagement cavity 31 of the sucking attachment 30 whereby the supportingmount can be easily and quickly assembled.

[0022] 2. The operation of the cranked driving control shaft 40 canforce a driven unit 20 which is engaged with the sucking attachment 30to drive down or lift up the skirted bottom area 33 to expel air in theskirted area out thereof via the vent holes 12 of the lid 10 to producevacuum state for fixing the supporting mount to a flat surface orintroduce air into the skirted area to get the sucking attachmentreleased.

[0023] 3.The supporting mount permits an umbrella to be easily andquickly fixed to a flat surface, such as a table or the roof of avehicle, and dismantled to carry around by way of the umbrella housingtube A, making the supporting mount of the present invention practicalin use.
